Description
AT 399 162 B
Die Erfindung betrifft einen Zusatz für Reibbelagmischungen, mit dem Reibungskoeffizient und Verschleiß gezielt eingestellt und Vibrationen reduziert werden können. Dieser Zusatz kann vorteilhaft in asbestfreien und bleifreien Reibbelagmischungen für hochbelastete Reibpaare, wie sie in Bremsen, Kupplungen, Synchrongetrieben etc. Vorkommen, eingesetzt werden. im allgemeinen müssen die Reibmaterialien in der Automobilindustrie folgende Eigenschaften besitzen: Der Reibungskoeffizient muß der speziellen Aufgabe angepaßt und über einen großen Bereich von Geschwindigkeiten und Temperaturen unabhängig von der Form und dem Alter des Materials stabil sein. Besonders wichtig ist es, daß der Reibwert auch nach extremen Temperaturbelastungen in der Kälte annähernd wieder seinen ursprünglichen Wert annimmt. Dieser Wert soll bei Scheibenbremsbelägen über 0,30 liegen. Das Reibmaterial darf sich nur wenig abnützen, darf aber andererseits die Bremsscheibe nicht stark angreifen. Um gute Komforteigenschaften zu gewährleisten, dürfen keine Geräusche auftreten. Die Empfindlichkeit gegenüber Feuchtigkeit muß möglichst gering sein. Darüberhinaus müssen sich solche Reibbeläge mit vertretbaren Kosten industriell herstellen lassen.
Es ist äußerst schwierig, alle an ein Reibmaterial gestellten Anforderungen zu erfüllen. Aus diesem Grund haben sich verschiedene Reibmaterialsysteme entwickelt, die dann für jeweils bestimmte Anwendungsgebiete optimal sind.
Reibbeläge aus reinem Kohlenstoff (oft kohlefaserverstärkt) sind von der Zusammensetzung her einfach und werden häufig für Flugzeugbremsen eingesetzt. Erste Versuche, dieses System für PKW-Scheiben-bremsen einzusetzten, zeigten jedoch fundamentale Schwächen auf.
Keramische Reibbeläge sind schon einige Zeit bekannt, konnten sich aber bisher nicht durchsetzen. Neuere Arbeiten auf diesem Gebiet lassen es jedoch möglich erscheinen, längerfristig PKW-Reibbeläge auf Keramik-Basis zum Einsatz zu bringen.
Sintermetalle sind eine weitere Basis für Reibmaterialien. Auf dieser Basis werden verschiedene Arten von Brems- und Kupplungsbelägen hergestellt: verschiedene Zusätze aus dem Bereich der Metallverformung haben sich als Hilfsstoffe bewährt.
Die kostengünstigste Art, Reibmaterialien herzustellen, ist auf Basis von Phenol- oder Kresolharzen. Der Großteil der PKW- und LKW-Beläge wird heute so produziert. Es werden hauptsächlich solche Harze auf Phenol-und Kresolbasis eingesetzt, die je nach Anwendung Thermoplast- oder Kautschuk-modifiziert sein können. Um solche Reibmaterialien den verschiedenen Anforderungen der Praxis anzupassen, müssen jedoch eine ganze Reihe anorganischer Zusätze wie Metalle, mineralische Fasern und verschiedene weitere anorganische Füllstoffe und Additive zugesetzt werden.
Bei den verstärkend und füllend wirkenden Stoffen wird heute kaum mehr Asbest verwendet. An dessen Stelle treten anorganische oder organische Fasern, wie z.B. Kohlenstoff- oder Aramidfasern bzw. Metalle in Pulver-, Span- oder Faserform. Auch verschiedene Mineralfasern und verschiedene Formen von Glimmer kommen zur Anwendung. Als Füllstoff wird hauptsächlich Bariumsulfat, MgO oder verschiedene Tonerden verwendet.
Die reibwertaktiven Füllstoffe teilen sich in Reibmittel und Gleitmittel. Sie sollen die Höhe des Reibwertes beeinflussen, für ein weitgehendes Gleichbleiben dieses Reibwertes bei verschiedenen Temperaturen sorgen und einen zu raschen Verschleiß des Reibbelags und des Gegenmaterials verhindern. Darüberhinaus sollen sie positiv auf die Geräuschentwicklung beim Bremsvorgang einwirken.
In diesem Zusammenhang wird auf "Friction Materials", Chemical Technology Review No. 100 Noyes Data Corporation, USA 1978 als relevanter Stand der Technik und als relevante Offenbarung Bezug genommen.
Eines der wichtigsten praktisch verwendeten Gleitmittel ist Bleisulfid (PbS). Obwohl PbS heute auch in vielen-auch nicht asbesthältigen-Belägen eingesetzt wird, versucht man bei Neuentwicklungen Bleisulfid durch andere Gleitmittel zu ersetzen.
Ein durch Bleisulfid nicht zu lösendes Problem ist die verlangte weitgehende Konstanz des Reibwertes bei Temperaturerhöhung (kein Fading) und die damit zusammenhängende möglichst gute Rückstellung des Reibwertes nach Temperaturbelastung (Recovery). Auf der Bremsscheibe soll sich kein Belag bilden, wobei der Verschleiß der Bremsscheibe nicht zu hoch werden darf. Überraschenderweise wurde nun gefunden, daß das im Vergleich zu Kupfer-Il-Sulfid als wirkungslos beschriebene Kupfer-I-Sulfid (vgl. US-PS 3 477 983) im Gegenteil einen sehr vorteilhaften Festschmierstoffzusatz zu harzgebundenen Reibbelagmischungen darstellt. Es stabilisiert in hervorragender Weise den Reibwert bei höheren Temperaturen. In dieser Hinsicht kann es vorteilhaft anstelle von Antimontrisulfid eingesetzt werden. Ein weiterer Vorteil ist die kostengünstigere Herstellung als die von Kupfer II Sulfid (CuS), das auch stärker hygroskopisch ist als das erfindungsgemäß eingesetzte Kupfer I Sulfid.
Gegenstand der Erfindung ist demgemäß ein Zusatz für harzgebundene Reibbelagmischungen, welcher dadurch gekennzeichnet ist, daß er teilweise aus Kupfer I Sulfid besteht. Kupfer-I-Sulfid (CU2S) kann 2
AT 399 162 B synthetisch aus den Elementen hergestellt werden.
In Abhängigkeit von der Basisformulierung des Reibbelags kann Kupfer-I-Sulfid gemeinsam mit Festschmierstoffen und anderen funktionellen Reibadditiven, auch nach vorhergehender Abmischung mit diesen, eingesetzt werden. Es kommen dabei andere Sulfide, Kohlenstoffträger wie Graphit und Koks, Phosphate s sowie verschiedene Oxide in Frage. Auch weiche Metalle können gegebenenfalls eingesetzt werden.
Mit Vorteil verwendbare Sulfide sind die Sulfide des Molybdäns, Zinks, Antimons, Eisens, Wolframs, Niobs, Titans. Von den Oxiden werden zur Einstellung des gewünschten Reibwertes bevorzugt Oxide des Aluminiums, Chroms, Kupfers, Eisens, Zinks, Antimons, Titans, Mangans, Molybdäns, Siliciums, Zirkons eingesetzt. 10 Unter den Phosphaten werden die im Anspruch 2 genannten und, bevorzugt die unlöslichen bzw. schwer löslichen Phosphate des Magnesiums, Kalziums, Bors, Aluminiums, Kupfers, Eisens, Zinks eingesetzt.
In den folgenden Beispielen wird nicht nur gezeigt, daß mit Kupfer-I-Sulfid asbestfreie Bremsbeläge mit sehr guten Gebrauchseigenschaften hergestellt werden können, sondern auch Beläge, die bleisulfidhältigen 15 Belägen durchaus ebenbürtig, wenn nicht sogar überlegen sind:
Beispiele:
Die Prüfung der erfindungsgemäßen Additive erfolgt an ganzen Bremsbelägen, um möglichst praxisna-20 he Verhältnisse zu schaffen. A. Herstellung der Beläge
Die Rohstoffe werden in einem Lödige-Chargenmischer FM 50 17 Minuten lang gemischt. Von dieser 25 Mischung werden der Belaggröße entsprechend ausgewogene Anteile in die Preßform einer Leinweber-Bremsbelag-Laborpresse eingefüllt und dort bei Temperaturen um 150° C gepreßt. Die Belagmasse wird dabei auf die vorher in die Form eingelegte eiserne Rückenplatte des Bremsbelags gepreßt und gleichzeitig mit dieser verklebt.
Nach dem Auskühlen der Beläge werden diese mit einer Zylinderkopfschleifmaschine oberflächlich plan 30 geschliffen, um eine volle Auflage auf die Bremsscheibe beim Test zu gewährleisten. Die so vorbereiteten Rohbeläge werden in einem Heraeus Umlufttrockenschrank bei Temperaturen bis 280 * C ausgehärtet. B. Prüfung der Beläge 35 Die Prüfung erfolgt mit einem Reibwertprüfstand RWS 75 der Firma Krauss, wobei Reibwert und das Verschleißverhalten der Beläge und der Bremsscheibe geprüft wird. Durch eine Einlaufphase mit 100 Bremsungen ä 5 Sekunden wird ein guter Kontakt zwischen Bremsbelagoberfläche und Bremsscheibe gewährleistet. Die folgenden Tests werden bei den Basistemperaturen 100° C, 200° C, 400° C und 500° C durchgeführt. Dabei wird durch Aktivierung der Bremse zuerst die Basistemperatur erreicht und dann von 40 dieser ausgehend 5 Sekunden gebremst und solange die Bremsscheibe wieder gekühlt, bis die jeweilige Basistemperatur wieder erreicht ist. Dieser Zyklus wird pro Basistemperatur 200 mal hintereinander durchgeführt. Nach diesen jeweils 200 Bremsungen werden die Bremsbeläge entnommen und sowohl bei den Belägen als auch bei der Scheibe der Gewichtsverlust gemessen. Daraus kann der Verschleiß errechnet werden. Der Anpreßdruck der Bremsbeläge ist 100 N/cm2, die während der Bremsung registrierte 45 Normalkraft ist die Grundlage für die Berechnung des Reibwertes. Die Auswerteeinheit des Reibwertprüfstands ist so konzipiert, daß der Reibwert mit Hilfe eines Schreibers aufgezeichnet werden kann. Daraus wird dann auch das Fading, die Reibwertdifferenz zwischen 100 und 500° C sowie die Recovery, die Differenz eines am Schluß bei 100* C gemessenen Reibwerts und dem anfänglich bei 100° C gemessenen Wert, bestimmt. so Die Belagverschleißwerte sind der Durchschnitt aus den Werten der beiden in einer Bremse eingesetzten Einzelbelägen.
Beispiel 1 (Vergleich) 55 Folgende Rohstoffe werden wie oben beschrieben gemischt, die Mischung verpreßt und die Beläge geschliffen, ausgehärtet sowie getestet. 3
AT 399 162 B
Vol % Kupferwolle 10 Talcum 20 Baryt 13 Polyarylamidfaser 10 Gummimehl 5 Friction dust 10 Phenolharz 25 CU2S 7
Folgende Resultate wurden erhalten:
Gesamtverschleiß des Belags: 41,2 g Gesamtverschleiß der Scheibe: 3,1 g Fading (u 100-400' C) 0,02 Recovery (n 100° C vor-nach) 0,01
Es zeigt sich, daß die Bremswirkung (charakterisiert durch den Reibwert) vor und nach einer Temperaturbelastung von über 400* C (üblich bei Talfahrten) fast völlig gleich bleibt und die Wirksamkeit der Bremse auch bei so hohen Temperaturen nur minimal abnimmt.
Beispiel 2 (Vergleich)
Es wird wie in Beispiel 1 verfahren, anstelle von CU2S werden jedoch 7 Vol% PbS eingesetzt. Folgende Resultate wreden mit den so hergestellten Reibbelägen erhalten:
Gesamtverschleiß des Belags: 85,9 g Gesamtverschleiß der Scheibe: 7,6 g Fading 0,08 Recovery 0,09
Hier ist doch ein deutliches Absinken der Bremswirksamkeit zu beobachten. Auch die Verschleißwerte sind deutlich höher als bei Verwendung von CU2S.
Beispiel 3
Es wird wie in Beispiel 1 verfahren, anstelle von CU2S werden jedoch eine Mischung aus 2,5 Vol% CU2S, 1 Vol% ZnS und 3,5 Vol% Tricalciumphosphat eingesetzt. Folgende Resultate werden mit den so hergestel-ten Reibbelägen erhalten:
Gesamtverschleiß des Belags: 34,3 g Gesamtverschleiß der Scheibe: 3,5 9 Fading: 0,02 Recovery: 0,02
Beispiel 4
Es wird wie in Beispiel 1 verfahren, anstelle von CU2S werden jedoch eine Mischung aus 2,5 Vol% CU2S, 1 Vol% ZnS und 3,5 Vol% Kaliumpyrophosphat eingesetzt. Folgende Resultate werden mit den so hergestellten Reibbelägen erhalten: 4
